Cometic C10120 MLS Head Gasket - 3.875" Bore x .040" Thickness

The Cometic C10120 is a premium Multi-Layer Steel (MLS) head gasket engineered for high-performance engine applications requiring precise sealing and durability. This gasket features a 3.875-inch bore diameter with a compressed thickness of .040 inches, making it ideal for custom engine builds and performance applications where precise compression ratio tuning is essential.

Key Features:

• Multi-Layer Steel construction provides superior sealing and blow-out resistance
• 3.875-inch bore diameter accommodates specific piston and cylinder configurations
• .040-inch compressed thickness allows for fine-tuning compression ratios
• Stainless steel construction with elastomeric coating for optimal sealing
• Designed to withstand extreme cylinder pressures in boosted and high-compression applications
• Eliminates the need for additional sealants or re-torquing
• Reusable design for engine disassembly and reassembly

Cometic MLS gaskets utilize multiple layers of stainless steel with a viton rubber coating to create a superior seal between the cylinder head and engine block. The embossed beads around combustion chambers and fluid passages provide concentrated sealing pressure exactly where needed, while the steel core layers absorb minor surface imperfections. This design makes the C10120 an excellent choice for race engines, turbocharged applications, and high-performance street builds where reliability under extreme conditions is critical.
